Aggregation Type
Aggregation Type UN/CEFACT code list.
Values add up (e.g. total GHG emissions across all facilities = sum of each facility's emissions)
Sum
The number of occurrences is counted
Count
Only the largest value across the set is meaningful
Maximum
Values are combined as an unweighted arithmetic mean
Average
Values must be averaged weighted by volume/output (e.g. emissions intensity per kg across suppliers)
Weighted average
Only the smallest value across the set is meaningful
Minimum
Only the most recent value is meaningful (e.g. a biodiversity assessment score where only the current state matters)
